Transfer expert Fabrizio Romano has explained why Michael Olise’s £35million move to Chelsea collapsed.

Olise looked to be heading to Chelsea after Chelsea reportedly activated his £35m ($45m)release clause this week. However, on Thursday, the 21-year-old signed a new four-year deal with Palace.

According to Romano, Crystal Palace considered going to a tribunal with Chelsea over Chelsea’s approach for the France Under-21 international – something they were reportedly unhappy about.

As a result, Chelsea pulled out of a move and Olise extended his stay at Selhurst Park.

Romano tweeted: “Crystal Palace informed club’s lawyers of their intention to consider going to a tribunal with Chelsea over approach for Olise.

“That’s how the story changed — Palace very strong on that and Chelsea left the conversations.

“Olise accepts new deal, Crystal Palace happy with that.”
